1,, all vi /mm if m (13 concern wilt it known that I, film; Sonia-nor,direc- \'entcd certain new and useful llllpl'tn't" nicnls in Cylindersfor t-lteuln-llngines end the liiltcyol which the following is u, specfication.

lily invention relates to improvements in cyliiulcrs for stezun enginesand the like, and more particularly to cylinders in which the stcuui orother pressure fluid is phased through the hollow cylinder heads hetorebeing admitted to tho'stean: chest or \lLlYQ casings. .\nd thoolrjcctol' the improvements is to provide :1 cylinder in which the l lilllwsupporting the cylinder is heutcd in it snniller degree by the steamlitlhlhlllg through the adjacent cylinder hcud.

With this object in view my invention consists in lirst passing thewhole of the steam through the hack cylinder head uiut then into theadjacent vol /e rinsing. where ii port of the steam is admitted to thecylinder, While the remainder passes through the front; cylinder heedand the second ruh'c casing.

In order Hint my invention he more clearly understood two examplesembody ing the seme have been shown in the 2n: couipnnying drowine.

In Fluid. drawing ligurc l, is n longitudinnl section of the, cylinder,and Fig. 2, ii similar section showing e modification of Fig. 1.

Referring more particularly to the ere :unple illustrated in Fig. 1, thecylinder 7 equipped with hack head a and n l'ront head 1), Both headsare made hollow end are provided with metros for admitting the steam orother pressure fluid, so that they are thoroughly heeled. At: both ends;steam chests or valve casing i2 and e ere provided through which thepressure fluid cen ulternntely be admitted to either end ol thecylinder, as is known in the art. As shown the back head a is prm'idcdwith on edlnission port; 0 through which the pressure fluid such assteam can he admitted, and it communicates with the adjacent; stciunchest (I' through u iois'sego 11-. The steam chest (I conununiciitesthrough u pipe f with the hollow of the front head I), und the latter isn nertcd through u passage 2' with the a jacent steam chest 0. hecylinder valves may have any suitahle construction, and may he onrrutedin :my preferred WE l The o crntion oi niy improved cy inklr willreuolly he understood. .The pressure thud. such us stczuu will firstpass through the hack head (I and to the steam chest at.

i ltlltl the latter :2 part of the steam will in ittiltlillttl to llilcylinder, while the renuiiuine' urt [lows through the pipe 1 t0- thefrom hcud o. und from the latter to the sic-tun chest w. lherc|y hothcylinder heads will thoroughly he ltlHlltitl. in the constructionde-crihed oil the stcuni passes lhrough the lmcli heed r1, while only upart thereof llows through the trout head I). This orren gcinent isiulvuntugcous in this respect, Eliot thereby from the front head whichrewires ins heat than the hurl: hcud uv smaller uniount of heel istransmitted to the frame of the engine which is connected with the trouthead. By my improved construction only one adn'iission pipe isnecessary, and furthermore I avoid the use of on admission pipe which islfirunchcd oil into two sections,

Patented Juno 3, 191 3.

u the modification shown in Fig. 2 the strum hdmission valve in isdisposed within the heck head, end its stem 1 is loculcd at the reur ol'the said head.

1' claim herein us my invention:

in a cylinder for steam engines and the like, the t'()ml)ilt lil()!lwith the cylinder having two strum chests or 'ulrc casings, of a fronthcud and ll hack head, and means to succecsivcly puss the ircssure fluidthrough the lmclt heed. one oi the steam chests, the front head, and thesecond one of the steam chest).

in testimony whereof l have hereunto set my hand in n iscucc of twosubscribing w il nesses.
